I need an experienced 3D CAD designer to create production-ready 3D models for a new line of custom eyewear frames. The design workflow will be based on 3D face scans provided via KIRI Engine. Since mobile 3D scans require precise scaling, you will need to calibrate and scale the mesh files using specific facial measurements I will provide (such as interpupillary distance / PD) to guarantee an accurate 1:1 fit before designing the frame. The digital CAD files will be printed locally using high-precision additive manufacturing. Since the frames sit directly on the skin for extended periods, the design must account for biocompatible materials (such as ISO 10993-compliant nylon, PEI, or optical resins). The end product is an optical component, so dimensional accuracy around lens grooves (for fitting lenses) and hinge mounts (for attaching the temples/arms) must be tight. I need you to advise on the best CAD tolerances and wall thickness based on the selected manufacturing process (SLS, MJF, or SLA). The final frame designs must support: Accurate scan calibration scaled to provided facial dimensions (e.g., interpupillary distance). Adjustable sizing (bridge width and temple length tweaks across SKUs). Unique design patterns applied to the surfaces based on provided vector textures. Compatibility for local 3D printing and post-processing/dyeing. Project Scope & Structure: Phase 1 (This Fixed-Price Project): Master Template creation, establishing hinge/groove tolerances, and setting up the scan calibration workflow. Phase 2 (Ongoing Client Orders): Per-client frame adjustments based on individual face scans. Please state your estimated per-frame rate for ongoing orders in your proposal. Deliverables: Scaled/calibrated 3D head models based on provided KIRI scans and PD measurements. Production-ready 3D CAD files for frames in STEP and STL formats (minimum three size variants). Material and print specification guide to hand off to my local 3D printing partner. Technical recommendations for tolerances on lens grooves and hinge mounts. Timeline: Phase 1 (Initial Setup & Master Template): 1 to 2 weeks. Phase 2 (Ongoing Customer Orders): Fast turn-around required (24–48 hours per custom frame model).

Hi there! Avatarist here. Engineering custom, scan-fit eyewear frames from mobile KIRI Engine meshes requires strict digital calibration—aligning mesh scale against Interpupillary Distance (IPD) before designing ergonomic, print-ready frames. Establishing precise V-groove lens geometry and hinge pin tolerances is critical so additive materials (like MJF/SLS PA12 nylon or SLA bio-resins) assemble cleanly without post-machining or lens popping. Using SolidWorks and Rhino/Grasshopper, I will calibrate your 3D face scans, establish the parametric Master Frame Template with custom vector texture mapping, and deliver a production handover spec for your local print partner. Deliverables (Phase 1): - Calibrated 3D Face Scan Workflow & Master CAD Template - Production-Ready Frame CAD Models (3 size variants in STEP & STL) - Technical Tolerance Guide for Lens Grooves (V-bevel) & Hinge Mounts - Print & Material Spec Sheet (SLS/MJF PA12 Nylon & SLA Bio-resins) Phase 2 Rate & Turnaround: - Turnaround: 24–48 hours per client scan https://www.freelancer.com/u/Avatarist Avatarist

Your project requires developing a production-ready eyewear CAD workflow rather than only modeling a frame, so the focus is on accurate face scan calibration, parametric design, manufacturing tolerances, and creating adaptable templates for future custom orders. I can assist with creating the calibrated head workflow, master eyewear template, lens groove and hinge integration, adjustable sizing variants, surface pattern application, and print-ready STEP/STL files. I’ll also provide recommendations for wall thickness, tolerances, and additive manufacturing considerations for the selected process. Could you please confirm which CAD platform you prefer for the master template and whether the initial frame design concept/reference geometry is already available?

Calibrating and scaling the KIRI Engine face scans using your provided measurements, like interpupillary distance, to achieve an accurate 1:1 fit is the hardest part of this job. I will use Geomagic Control X for the scan calibration and scaling, then import those meshes into SolidWorks for the frame design. The frame design will use shell features and precise extrusions to create the lens grooves. I would build the nose pads first, so that their interface with the scaled face mesh is established, then design the rest of the frame around that secure point. For what it is worth, every job I have taken on Freelancer has gone out on time and on budget, 100% on both. This approach ensures the accuracy from the 3D Rendering stage carries through to the final 3D CAD files ready for additive manufacturing. Will the final lens groove dimensions be a fixed size, or should they accommodate a range of standard lens thicknesses? I propose a short call on Freelancer to settle the scope, covering scan calibration tolerances and lens groove specification.

Hi there I will create the production ready 3D models for your custom eyewear frames using the KIRI Engine scans you provide. I will first calibrate the face mesh against the supplied facial measurements then build the frame geometry in SolidWorks ensuring proper scaling and manufacturability. The workflow matches my recent work on an Android arcade game where precise geometry and quick iteration were essential, so I can deliver a clean, ready‑to‑print model within the budget. I can finish the full model and a test print ready file in five days. Will the frames include any hinge mechanisms that need moving parts Will you need separate STL files for each eye side or a single mirrored assembly
